Abstract: A pipe clamp (20) for inhibiting fluid flow through a flexible pipe, comprising first (21) and second (22) contact members for positioning on opposing sides of a flexible pipe, and actuation means (29), optionally a pyrotechnically driven piston actuator, for automatically urging the contact members together, such that in-use a flexible pipe can be pinched closed. Particularly suited to inhibiting fluid flow in pipework under repair, or emergency shut off of fluid flow in failed pipework. Also relates to a pinch valve and method of use.
